The company will continue providing brownfield engineering services to support the onshore and offshore Gorgon and Wheatstone LNG assets, plus the Barrow Island and Thevenard Island oil projects, all offshore Western Australia.

This extension adds two years to the five years the company already had the contract and there is an option for an additional two-year term, and then an additional one-year term.

The contract will be serviced from WorleyParsons' Western Australian offices.

"We are proud that Chevron continues to choose WorleyParsons and we look forward to growing our relationship with Chevron," CEO Andrew Wood said.
